Ingredients You’ll Need
- 1 pound flank steak, sliced thin against the grain: Flank steak is perfect for this dish as it becomes incredibly tender when cooked properly. You can substitute it with sirloin if needed.
- 1/4 cup cornstarch: This helps create a crunchy exterior on the beef when cooked. Ensure it’s evenly coated for the best texture.
- 1/3 cup water: Used to create the sauce’s perfect consistency. Filtered water usually works well.
- 1/4 cup low sodium soy sauce: Provides the salty, umami flavor. Opt for low sodium to keep the dish balanced.
- 1/2 cup brown sugar, packed: It adds a rich sweetness to the sauce. Light or dark brown sugar both work well.
- 2 teaspoons cornstarch: This is in addition to the first cornstarch, helping thicken the sauce to a luscious texture.
- 1/4 cup vegetable oil: For frying the beef, choose a flavorless oil like canola or grapeseed.
- 2 garlic cloves, minced: Garlic gives depth to the flavor profile. Freshly minced is best for a robust taste.
- 1 tablespoon minced ginger: Ginger adds freshness and warmth—fresh is always recommended for maximum zest.
- 4 green onions, cut into one-inch pieces, with the whites and greens separated: The white parts contribute savory notes while the green tops add a pop of color at the end.
How to Make Mongolian Beef So Good You’ll Skip Takeout Forever
Prep the Beef: In a large bowl, combine the flank steak and 1/4 cup of cornstarch, tossing well to ensure the meat is thoroughly coated. This will help seal in the moisture and provide a delightful crunch when cooked. Set aside to marinate for about 15 minutes.
Make the Sauce: In a small bowl, whisk together 1/3 cup water, 1/4 cup low sodium soy sauce, 1/2 cup packed brown sugar, and 2 teaspoons cornstarch. The mixture should be smooth. This sauce will enhance the beef’s flavor and provide that signature sticky glaze—set it aside.
Cook the Beef: In a large skillet over medium heat, add 1/4 cup vegetable oil. Once it shimmers, add the marinated beef in batches, making sure not to crowd the pan, to keep it from steaming. Cook for about 3 to 5 minutes until the beef is browned. It should be crispy on the edges but tender inside. Remove the beef and let it rest on a plate tented with foil to keep it warm. Drain the oil from the pan, leaving about 1 tablespoon.
Sauté the Aromatics: With the remaining oil, add the minced garlic and ginger, plus the white parts of the green onions. Sauté until fragrant, about 30 seconds. Be careful not to burn the garlic; it should smell warm and inviting, not acrid.
Add the Sauce: Pour the sauce mixture into the skillet, scraping up any browned bits that have stuck to the bottom. Bring it to a simmer, cooking until thickened, about 1 minute. It should bubble slightly around the edges.
Combine and Serve: Return the cooked beef to the skillet, tossing everything together to coat in the glossy sauce. Garnish with the reserved green onion tops. Serve it steaming hot over a bed of fluffy rice, and enjoy your homemade Mongolian Beef!
Storing & Reheating
To store leftovers, let the Mongolian Beef cool down at room temperature for no more than two hours. Place it in an airtight container and refrigerate for up to 3 days. For longer storage, you can freeze it for up to 3 months. Just ensure it’s in a freezer-safe container, and when you’re ready to enjoy again, thaw it in the refrigerator overnight. Reheat on the stove over low heat for 5-8 minutes until warmed through, adding a splash of water if needed to revive the sauce. The texture may be slightly different after freezing but is still delicious.
Chef’s Helpful Tips
- Avoid overcrowding the pan when cooking the beef. This prevents proper browning, which is key to flavor.
- Make sure the skillet is hot enough before adding the beef. This helps achieve that crispy exterior.
- If you can, use fresh garlic and ginger for the best flavor. You can always finely grate the ginger to dissolve in the sauce quickly.
- For an extra kick, feel free to add a dash of chili flakes or sriracha to the sauce.
- This dish is fabulous served with steamed broccoli or bell peppers tossed in for added nutrition!
Mongolian Beef is not just another recipe in your collection; it’s a comforting dish that’s effortlessly flavorful and quick to prepare. Plus, it’s budget-friendly, making it a win-win for any home cook! I hope you take it for a spin and make it your own by adding personal twists like some vibrant vegetables or tweaking the sweetness to suit your taste. Trust me; once you experience this recipe, you might just find yourself skipping takeout forever!
